“A PMU in Every Household? GPS Time Synchronized Wide-Area Power Grid Monitoring” with Yilu Liu, University of Tennessee, Knoxville, Oak Ridge National Laboratory

The talk will introduce the research activities of power grid wide-area monitoring and some fascinating observations that were revealed for the first time. The critical roles of wide-area synchronized measurement in situation awareness, operation, and control will be discussed. The concept of electro-mechanical wave propagation in power grid will be demonstrated using measurement data collected from the actual US grid. The forensic value of grid signature in digital audio/video authentication will be introduced, as one of the surprising by-products of this technology.

Speaker: Dr. Yilu Liu is currently the Governor’s Chair at the University of Tennessee, Knoxville (UTK) and Oak Ridge National Laboratory (ORNL). She is the deputy director of the NSF/DOE Engineering Research Center - CURENT. Prior to joining UTK/ORNL, she was a Professor at Virginia Tech. She led the effort to develop the North America power grid monitoring network (FNET) at Virginia Tech which is now operated at UTK and ORNL as FNET/GridEye. Her current research interests include power system wide-area monitoring and control, large interconnection level dynamic modeling and simulations. Dr. Liu is a fellow of IEEE and the recipient of the Presidential Faculty Fellow Award.
